3-D printer A means of producing physical items — including toys, foods and even body parts — using a machine that takes instructions from a computer program. That program tells the machine how and where to lay down successive layers of some raw material (the “ink”) to create a three-dimensional object. biologist A scientist
adaptation (in biology) A process by which an organism or species becomes better suited to its environment.

WASHINGTON, D.C. — On a weekend where the nation’s capital was focused on hosting its first World Series games in seven decades, 30 young researchers from across the nation were on deck for a hard-hitting competition of their own. In a sense, all were winners already. Each had, after all,
Washington, D.C. — A device that harnesses the same aerodynamic effect that makes a curveball swerve might one day boost aircraft safety. How? Such a device could prevent some aircraft stalls and spins. Such instabilities underlie one in every 10 small-plane accidents in the United States, notes Rylan Gardner. The
The stems of sunflowers move throughout the day so that their flowery heads always squarely face the sun, wherever it is in the sky. This phototropism (Foh-toh-TROAP-ism) helps the plants soak up maximum amounts of sunlight. Scientists had trouble copying this ability with synthetic materials. Until now. Researchers at the
anatomy (adj. anatomical) The study of the organs and tissues of animals. Or the characterization of the body or parts of the body on the basis of its structure and tissues. Scientists who work in this field are known as anatomists. average (in science) A term for the arithmetic mean, which is
People might one day grow meat in factories instead of having to harvest it from farmed animals. So far, attempts at lab-grown meat haven’t managed to match the texture of the animal muscles eaten as meat. Scientists have been working to coax cells to organize into something like the fibrous
Preparing ourselves for extreme events As wildfires raged through the Swedish forests in 2018, a new set of European resilience management guidelines for dealing with crises was demonstrating its potential usefulness to decision-makers. Applying these recommendations can save many lives and protect major infrastructure assets during cross-sectoral accidents and crises.
